GPU rendering works but only after I open the system menuhttps://blenderartists.org/forum/showthread.php?445743-GPU-rendering-works-but-only-after-I-open-the-system-menu&goto=newpost
Thu, 15 Feb 2018 12:24:10 GMTThis is a minor issue, but I'm completely flummoxed.
Here's a quick step by step.
My GPU option is greyed out upon opening Blender.
I open User preferences>System. My GPU box is already checked under the CUDA section.
I close the User Preferences window.
Suddenly GPU is no longer greyed out and works perfectly.

I tried on both 2.79 and 2.78. Same thing.

I tried running Blender from the terminal and get no error message.

This is with Manjaro Linux, Threadripper 1950x, GTX1070

Anyone with a similar issue or ideas to clear up the mystery?

Thu, 15 Feb 2018 08:15:43 GMTHey everyone,

Since I updated to Blender v2.79, I have had a somewhat annoying problem that I can't seem to fix!

I work on a system that has 3 monitors, so I have developed a custom UI layout to make use of this. This has never been a problem before and whenever I have opened blender, clicked on the file name to open the project, everything loads as it should across the 3 monitors.

However, v2.79 doesn't seem to like this. If I try to click on a file name the program simply shuts down. I have to go to File > Open etc and then uncheck 'Load Custom UI'. Then the project will open but with the default UI layout which I then have to change to my preferred layout every time.

Whilst this is a workaround, It's a pain having to do this every time I open Blender.

Does anyone know how I can fix this issue permanantly? I have tried uninstalling & reinstalling, even to a different location but the problem persists.

I haven't tried reinstalling v2.78 as that seems a bit of a backwards step at this point.

Any help would be greatly appreciated!

This happens very seldom and my scen is very small compared to what I have done before without Blender crash. Before I started to work with Blender today, there was an update for Windows 7. Could that be the reason? Any other Blender users having problem?

Tue, 13 Feb 2018 22:03:48 GMTHello guys, new member here :) I'm running blender 2.79 on an Intel i7-8700 CPU 3.20GHz - cores, with 16Gb of ram. I made 40 metaball copies and i noticed very slow response when i selected all and tried to move them in the view port although the amount of memory used was only around 1.5Gb. Is this natural or i miss something with blender settings? P.S. I use Linux Debian O.S.

Just got the 3d Connexions wireless set (includes the CAD Mouse). On my MAC Pro (latest OS) the Spacemouse works just fine mostly in Blender 2.79 and I really like it.

However, on my main WINDOWS-10 machine, I cannot get the 3d MOUSE PROPERTIES CONTEXT MENU to pop up using the LEFT BUTTON on the space mouse as it does on the MAC. Because of this, all the AXIS of the space mouse are reversed: UP is DOWN, LEFT is RIGHT, ROTATE COUNTER CLOCK is ROTATE CLOCK WISE.

I've read a number of posts here and followed many of the instructions meant to make the spacemouse work in Blender but none of them work.

So questions:
Why does the 3d Mouse Context menu work in the Apple OS but not in Windows-10?
How do I get it to work in Windows 10?
Neither of the buttons on the spacemouse work in Windows but work just fine on the MAC. Why?

Any, all help and suggestions are appreciated.

Thanks

Does having multiple GPUs improve the preview speed? I'm aware it speeds up rendering since each GPU handles a tile. But does that work for the preview also?

Sorry if this question has already been asked. When I search 'multiple GPUs' on blenderartists I get dozens of threads that don't answer my question.

Tue, 13 Feb 2018 10:03:35 GMTI have a rendering problem I can't solve. This image a simplified version of the project for demo purposes. A ring of lights inside a mirrored tube is the goal. I would imagine we would mostly see the nearest lights reflecting in the mirror cylinder just below the light. But what we end up seeing is this. Depending on the camera position it changes a bit but not as expected. The big problem I'm facing is this point in the tube where there is basically no reflection at all under the lights. I've done lots of tests and nothing led to a solution. (Flipping normals, smoothing, flat, Subdivision Surf, etc.) I feel like maybe someone has experienced this or knows the answer. Thank you.

Mon, 12 Feb 2018 16:59:22 GMTI've been using blender to model a variety of parts, mainly because I'm more comfortable using blender for making my .stl files for 3D printing. Recently I've modeled something with parts that although assembled in 3D, need to be laser cut in 2D, and I haven't got the foggiest clue how to go from Blender --> 2D cut outs.

First of all, I'm pretty new to Blender, and I'm still in my learning stage, so I'm sorry if my question sounds dumb to you.

I'm trying to create a keyboard 3D model, and when I started, I was wondering whether there was a way to easily update all same keys at once. Then, I found linked duplicates from the Blender documentation.

With this information, I made this:

Now, I would like to map all keys UVs to match the corresponding part of my texture. But UVs seem to be linked too with linked duplicates.

I know it's possible to break this link, but I want to keep the same geometry for each kind of key. Do you know if there is a way to do what I want ?

I'm having an issue where Blender 2.79 repeatedly stops working and needs to close.

It is happening consistently when making simple adjustments to the Principled BSDF shader in 'rendered view'

For example, this morning I had a very simple studio HDR environment loaded, then I added an image texture to the base color of a simple sphere mesh, adjusted the metallic slider and BOOM 'Blender has stopped working and needs to close'. Opened up a new file, repeated the process and once again Windows reported it needed to close.

Any ideas?!

I believe it has something to do with the cage mesh because cageless bakes work fine. Any insight would be appreciated. test.blend

note: this is from a larger .blend where the normal bakes were taking +30 minutes for no discernible reason, so I copy/pasted them in a new scene to troubleshoot. Now I find myself troubleshooting this :mad:

I'm trying to automatically fill holes in an "arbitrary" mesh. I first select all boundary vertices by using "Select non-manifold" and then enabling only "boundaries". Selection looks typically like this:

After this I have tried to fill faces to boundary loops, and this is the result:

I really wonder why does Blender (I'm using 2.79 here) connect those unconnected islands together, and is there some command which would create faces to only connected vertex islands?

I'm trying to create a Python script which would automatically process and clean up these meshes for me, so I can't rely on manual cleaning.

I have tried to use following Python commands for this filling stage, but all of them sooner or later create faces between completely unconnected vertices:
